[maintainer] refactor(plugin-security): split src/security-plugin.ts (10,746 lines, +2,803 in 30 days) along its SecurityPlugin seams, one move-only slice per PR

Filing gate ③: a task the maintainer dispatched, quoted verbatim below. Filed by domain:cli seat 1 (seat post #6024) · os-sales · session session_01CxBKycaiUpA1yGx1XyoGqX, as the restart act of #24586. ⛔ Not a claim.

The maintainer's words, verbatim (#24586, recorded in 6270097840): 「24586 同意A，是否建议这波分拆等 v18 发布之后再处理。」 The restart condition (npm @objectstack/spec latest ≥ 18.0.0) was read true by triage in 6291735609. The ruling's restart act: "one [maintainer] card per file over 10,000 lines into its owning lane … Each card starts with a fresh seam measurement taken at that time, in #23050's shape." This file was under the line at the ruling (7,943 lines 30 days ago) and is over it now, so the ruling's per-file rule covers it.

Reader who acts: the domain:services seat (packages/plugins/plugin-security is that lane's), one dispatch per slice.

Measured (on `origin/main` `123ff6f4e`, 2026-10-22)

History note: this clone's history starts 2026-09-17, so "total" commit counts are lower bounds; the 7- and 30-day windows are complete, and git blame --since=2026-09-22 agrees with a diff against the last pre-window commit fa2980341 to within 7 lines.

Size and churn: 10,746 lines (7,943 thirty days ago: +2,803, +35.3%). 20 commits in 7 days, 98 in 30 days. git blame --since=2026-09-22 attributes 4,847 lines (45.1%) to the last 30 days.
Structure: a 1,247-line module preamble, then one SecurityPlugin class (9,499 lines, 124 members). start() alone is 3,197 lines: setup and service registration, the main ql.registerMiddleware authz middleware (2,203 lines), a second middleware, bootstrap and the org-admin auto-grant. The largest sections:

section	lines	lines from the last 30 days
`start()`: main `ql` authz middleware	2,203	918
controlled-by-parent (`resolveCbpRelation`, `computeControlledByParentFilter`, `assertControlledByParent`)	1,541	774
module preamble	1,247	571
read filters + field masks + object admission (`getReadFilter`, `canReadObject`, `canWriteObject`, …)	1,083	795
addressed writes + RLS filter layers + tenant wall	1,075	309
baselines + `explainAccessForCaller` + sharing verdicts	936	470
policy collection, object security meta, outage probes	719	259
`start()`: setup + service registration	623	229

Shared state a split must pass: ql (61 refs), permissionEvaluator (57), logger (43), resolvePermissionSetsForContext (30), tenancyPosture (27), the field-name and CBP caches. The start() middleware closes over locals and calls into nearly every later section, so it is the costliest slice; the CBP, RLS and read-filter sections share the caches.
What reads it by path: 9 scripts/ files, including the ADR anchor scripts/adr-anchors/packages__plugins__plugin-security__src__security-plugin.ts.json (ADR-0055, ADR-0106, ADR-0123, ADR-0138; its invariant names resolveCbpRelation, which a CBP slice moves), check-position-name-fold-loaders.mjs, check-system-context-census.mjs, symbol-anchors.mjs and three contract baselines; 28 files under content/ and docs/; 171 test files.
In flight: 2 of the 10 open PRs touch the file: fix(objectql,plugin-security): the write preview answers a row's organization from the tenant wall's own verdict #25215 (draft, +560/−297) and fix(plugin-security): a controlled_by_parent detail's read scope is the engine's ReadableIds leaf over its master (ADR-0139 D6, seventh consumer); Q2 A in service-analytics; the Turso remote nested leaf #25198 (draft, +191/−191, the CBP read scope). Slices touching their regions wait for them.
⚠️ This is a permission boundary. Move-only is the whole contract here: a slice that changes any verdict is out of scope.

The ask (from #24586's ruling and #23050's shape)

Split along the existing seams, one area per PR. Each slice is move-only: no logic changes.
Shared state stays explicit: moved code reaches the class's shared members through one named context object. ⛔ Not a second copy of a helper, ⛔ not a re-derivation.
Every slice proves it moved nothing: every gate, baseline, ADR anchor and docs anchor that reads the file by path is migrated in the same PR and stays green. ⛔ A gate whose target moved must not go silently empty.
Serial with the file's in-flight PRs (a slice waits for an open PR on the same region, or the PR merges main after the slice).
⛔ No new gate.

Not in this card

Any behaviour change. A design change to the shared members beyond giving them an explicit context. Splitting files in other lanes (#24586 hands those to their own seats).

packages/plugins/plugin-security/src/security-plugin.ts is changed by open PRs #25215 and #25198 (#24932, with the maintainer), and #25095 (p2, security, queued ahead of this card) lands in its detail write gate.

Prerequisites, read in this act: #25215, #25198 and #25256 (#25095) are all MERGED; none of the 13 open PRs touches packages/plugins/plugin-security/src/security-plugin.ts (each head diffed against its own merge base with origin/main), so the serial note 6341975560 is cleared.

Seam measurement, origin/main 72fad922 (TypeScript compiler API over the file; the file is 11,054 lines, the class SecurityPlugin 9,672 lines and 125 members). The plan below is provisional: each cut is re-measured on the merged file before it is cut, and moves exactly one area.

cut	area	members (line range at `72fad922`)	lines
1	leaf readers: RLS policy collection, unresolved-posture probes, field-level masks, field-name tables	`collectRLSPolicies` .. `extractTargetField`, the class tail `:10338`-`:11053`, except `getObjectSecurityMeta`	~606
2	controlled-by-parent read derivation	`resolveCbpRelation`, `reportCbpMasterUnresolved`, `reportRejectedReferenceAlias`, `computeControlledByParentFilter`, `controlledByParentChainRefusal` (`:8827`-`:9258`); the ADR anchor whose invariant names `resolveCbpRelation` migrates in the same PR	~432
3	controlled-by-parent write gate	`checkControlledByParentWrite` .. `assertMasterRowEditable` (`:9431`-`:10336`)	~906
4	write tenant wall and operation principals	`computeWriteTenantCheckFilter` .. `writeWallVerdict` (`:8330`-`:8825`), `resolveOperationPrincipals`, `refuseGuestWithoutOrganization` (`:9260`-`:9429`)	~666

7	read filters, field readers, object admission	`getReadFilter` .. `canExport` (`:5816`-`:6900`)	~1,085
8	explain, sharing verdicts, authored row write, baselines	`declareEveryone` .. `checkAuthoredRowWrite` (`:4880`-`:5814`)	~935
9+	`start()`: the main `ql` authz middleware (closes over `start()`'s locals), setup and service registration, `init` and the seed-ownership claim	`:1725`-`:4878`	~3,150

Module preamble (:1-:1381): a top-level declaration moves with the cut whose bodies alone read it. One cited by a symbol anchor in a file this project does not own (packages/spec/liveness/*.json, e.g. security-plugin.ts#normalizeRequiredPermissions) stays where it is, so getObjectSecurityMeta stays in the class with it for now.

File surface, cut 1 (stop on a breach and explain it in the report). Move-only, per the card's ask 1-5:

packages/plugins/plugin-security/src/security-plugin.ts: the bodies of 16 private methods leave for ONE new module beside it, packages/plugins/plugin-security/src/security-plugin-object-inputs.ts, with the module-level declarations only they read (isDelegatedPrincipalLeg, the imports only they use). The class keeps each method (name, signature, docblock, position) and hands its body one host literal of exactly the members that body reads, each typed as the class member (SecurityPlugin['m']), methods as late-bound closures, fields reassigned after construction as getters ([maintainer] refactor(rest): split packages/rest/src/rest-server.ts (13,701 lines, 70 commits in 30 days) along its register*Endpoints seams, one move-only slice per PR, /meta after #22877 stage 2 #23050's shape B, as [maintainer] refactor(service-automation): split src/engine.ts (13,735 lines, +2,199 in 30 days) along its AutomationEngine seams, one move-only slice per PR #25222 and [maintainer] refactor(plugin-auth): split src/auth-manager.ts (10,338 lines, +1,867 in 30 days) along its AuthManager seams, one move-only slice per PR #25224 cut 1 apply it).

Comment only.
Every gate, baseline, ADR anchor, docs anchor and test that reads a moved line by path moves in the same PR and stays green. ⛔ No gate is loosened, and none goes silently empty. A reader in another lane's file is a declared cross-lane touch, or the cut is narrowed so it is not needed.
.d.ts: ruling 6348891160 item 1 — the published dist/index.d.ts and dist/index.d.mts keep the same declaration set (no private member made public or protected, nothing added, removed, renamed or retyped), are byte-identical to base after sorting the members of each string-literal union and nothing else, keep identical ESM and CJS export lists, and every raw-diff line is a union-member-order swap. Any other diff kind stops this thread with needs_decision.
No changeset (skip-changeset, ruling 6348891160 item 4).
⛔ Not touched: getObjectSecurityMeta, every other section of the class, any behaviour.
Container & model: L series (one cut per PR, strictly serial in this thread), card thread (in-session executor), model: default tier (dispatch-gates.mjs --tier --repo objectstack-ai/objectstack: "no path-derived mandate"), effort: xhigh (permission boundary). Each cut goes back to the services seat 1 for ACCEPT before the next starts. A cut over 3000 changed lines lands by human merge.

Seat: domain:services#1 (seat post #6021)
Ruling-ref: 6348891160 (the series' .d.ts bar, item 1)

Prerequisite, read in this act: #25290 is MERGED (f47f7f222f, landed note 6351823134).

Serial check, read in this act: of the 14 open PRs, one touches packages/plugins/plugin-security/src/security-plugin.ts: #25288. Its head was diffed against its own merge base with origin/main (cc8d886d). Its hunks are in the import block, in start, in :5146-:6837 (explain, delegated read filter, field readers) and in resolveOperationPrincipals. At that merge base the cut-2 members sit at :8775-:9204, so no hunk of #25288 lies in them. The two changes are disjoint, and whichever lands second takes a plain merge of main.

Seam re-measured on the merged file (f47f7f222f, 10,929 lines). The cut-2 members are at the same lines the plan named: resolveCbpRelation :8827, reportCbpMasterUnresolved :8963, reportRejectedReferenceAlias :9020, computeControlledByParentFilter :9092 and controlledByParentChainRefusal :9219-:9258. All five are synchronous. Between them they read the members cbpRelCache, ql, logger and each other.

Module-level declarations, classified by who reads them (TypeScript checker over the file):

These move with the cut, because only the moved bodies read them: CBP_LEAF_READ_VERBS, masterNotWritableRefusal, and the imports ReadableIds, controlledByParentMasterRefusal (with its comment) and OWD_DELEGATING_ROW_WRITES.
These stay: CBP_MAX_CHAIN_DEPTH, which the write gate also reads and which ADR-0055 anchors by symbol (security-plugin.ts#CBP_MAX_CHAIN_DEPTH); CbpRelation, which the write gate also reads; and RLS_DENY_FILTER and masterGovernsRowWrites, which the module imports from their own modules.
The module reads CBP_MAX_CHAIN_DEPTH through an import from security-plugin.ts, so that declaration gains export. index.ts re-exports only SecurityPlugin, so the published surface does not move. The module names CbpRelation through the return type of SecurityPlugin['resolveCbpRelation'], so the interface needs no new export.

The any-erasure baseline (scripts/query-options-erasure-baseline.json, under ruling on #25224): security-plugin.ts is not one of its keys, the query-options/no-any-erasure rule runs on the file with no exemption, and the cut's range holds no as any at all. So that ruling does not reach this cut.

File surface, cut 2 (stop on a breach and explain it in the report). Move-only, per the card's ask 1-5:

packages/plugins/plugin-security/src/security-plugin.ts: the bodies of the five methods above leave for ONE new module beside it, security-plugin-cbp-read.ts. The module-level declarations that move are the ones listed above. Each method stays in the class with its name, signature, docblock and position. Each hands its body one host literal of exactly the members that body reads (CbpReadHost, each member typed SecurityPlugin['m']). Methods go as late-bound closures, and every field read goes as a getter: cbpRelCache is not declared readonly, and start() assigns ql and logger. This is [maintainer] refactor(rest): split packages/rest/src/rest-server.ts (13,701 lines, 70 commits in 30 days) along its register*Endpoints seams, one move-only slice per PR, /meta after #22877 stage 2 #23050's shape B, as cut 1 applied it.
scripts/adr-anchors/: ONE new entry for the new module, carrying ADR-0055 and the §1 invariant of the existing security-plugin.ts entry. That paragraph describes the master derivation, which is now realized there. The security-plugin.ts entry stays unchanged: the method, its docblock and the write half that consumes the derivation remain in that file, and dropping the paragraph there would loosen that file's anchor.
Every gate, baseline, docs anchor and test that reads a moved line by path moves in the same PR and stays green. ⛔ No gate is loosened, and none goes silently empty. Both ADR symbol anchors that name this area, security-plugin.ts#computeControlledByParentFilter (ADR-0055, ADR-0139) and #CBP_MAX_CHAIN_DEPTH, keep resolving with no edit, so docs/adr/** is not touched.
.d.ts: ruling 6348891160 item 1, with the same four-hash block, normaliser, raw line count and positive control as cut 1. Any other kind of diff stops this thread with needs_decision.
No changeset (skip-changeset, ruling 6348891160 item 4).
⛔ Not touched: the write gate (checkControlledByParentWrite onward, cut 3), every other section of the class, any behaviour.
Container & model: L series (one cut per PR, strictly serial in this thread), card thread (in-session executor), effort: xhigh (permission boundary). The cut goes back to the services seat 1 for ACCEPT before cut 3 starts. A cut over 3000 changed lines lands by human merge.

Ruling: needs_decision fork review (project review thread 「#25223 ADR 锚点裁决」) · letter A · maintainer 「对于这种类似的问题，能否你自己开一个单独的 fable thread 做评审，对于自己有把握决定的问题，自己决定，不能决定的开决策卡？」 2026-10-22T22:52Z

Proxy ruling under the maintainer's delegation quoted above (carried into this project by its owner's standing rule 「卡线程报 needs_decision 时，另开 fable 裁决线程，有把握就裁并把裁决落在 GitHub 上，没把握才给 Bill 发决策卡」), by the review thread's session session_01XtTny7MNZWVR3HdqvRigrN (project thread), on the domain:services seat 1 card thread's needs_decision fork for cut 2 of this card (claim 6352049267, session session_017BoLT8Gaa8t9a7AWVH8qZa; the fork reached the coordinator from the thread and is recorded on this card for the first time here). The card thread's next comment here carries Ruling-ref: this comment's id. Marker: auto-adjudicated. ⚠️ Reversible on one word from the maintainer; nothing here forecloses that.

The question

Cut 2 as claimed in 6352049267 moves the five controlled-by-parent read-derivation bodies (resolveCbpRelation, reportCbpMasterUnresolved, reportRejectedReferenceAlias, computeControlledByParentFilter, controlledByParentChainRefusal) out of security-plugin.ts into security-plugin-cbp-read.ts. At its head 94ef3e320f (base 5801a4f2, which is origin/main at this write) the 62 derived gates are green, the .d.ts four-hash block holds and the plugin-security suite is 210/210, but node scripts/check-adr-symbol-anchors.mjs, which CI runs (.github/workflows/lint.yml, step adr-symbol-anchors-resolve-no-line-numbers) and dispatch-gates --commands did NOT derive for this change set, exits 1 at the head and 0 at the base:

docs/adr/0055-master-detail-controlled-by-parent.md:26 security-plugin.ts#sharingModel — unresolved-symbol
docs/adr/0055-master-detail-controlled-by-parent.md:58 security-plugin.ts#controlled_by_parent — unresolved-symbol

Both anchors sit in sentences about the WRITE half of ADR-0055 — Context item 3, 「By-id write pre-image check (#1994). …security-plugin.ts#sharingModel already re-reads the target row under the write-op RLS filter before an update/delete and denies if invisible. This is the exact hook to extend with a master-access check.」, and §3, 「In the pre-image block (…security-plugin.ts#controlled_by_parent), for a controlled_by_parent detail update/delete/create」 — yet both resolve only on tokens inside the READ derivation. docs/adr/** is Tier H (AGENTS.md Prime Directive 14): an edit there lands only on the maintainer's APPROVED review. The fork:

A (the card thread's recommendation, in its second, narrower reading) — cut 2 moves only resolveCbpRelation and its two reports reportCbpMasterUnresolved and reportRejectedReferenceAlias into a new module security-plugin-cbp-relation.ts; computeControlledByParentFilter and controlledByParentChainRefusal stay in security-plugin.ts with the declarations only they read; the module keeps a type-only import of the class (cut 1's shape) and CBP_MAX_CHAIN_DEPTH needs no export; the two misdirected anchors go on record as an out-of-scope finding and are repointed in a separate Tier H docs PR.
B — repoint the two anchors inside the cut-2 PR; the whole PR becomes Tier H and waits for the maintainer.
C — a separate Tier H docs PR first; cut 2 in its five-body shape waits for it to land.

This thread's re-measure

Fresh clone at 5801a4f2. node scripts/check-adr-symbol-anchors.mjs: base exit 0 (2383 anchors across 142 records resolve); head 94ef3e320f in a worktree: exit 1 with exactly the two findings above. Then every ADR symbol anchor naming security-plugin.ts — 28 anchors across 10 ADRs — was mapped to the lines it resolves on, with extractAnchors and symbolResolutionClass from scripts/symbol-anchors.mjs (the gate's own resolver, comments stripped as it strips them):

#sharingModel (ADR-0055:26) resolves as declaration on ONE site, base :9208, const sharingModel = schema?.sharingModel ?? …, a local inside computeControlledByParentFilter. Its only other spelling in the file is a docblock (:9121), which the resolver strips.
#controlled_by_parent (ADR-0055:58) resolves as literal on THREE sites: :9035 (a quoted token inside a template literal in reportCbpMasterUnresolved), :9209 (computeControlledByParentFilter) and :9275 (controlledByParentChainRefusal). Its 23 other spellings are comments and docblocks (:546–:615, :5857, :7349, …), stripped before matching.
⭐ The write half the two sentences describe — checkControlledByParentWrite :9492 through assertMasterRowEditable :10132 — holds no 'controlled_by_parent' token and binds no sharingModel. These two anchors have never pointed at the mechanism their sentences name; they resolve by coincidence of spelling. The gate's header says why it cannot see that: 「It verifies that the anchor POINTS AT SOMETHING REAL. It cannot verify that the sentence around the anchor is TRUE about that code.」
The narrowed cut, simulated on the base file by blanking :8884–:9199 (the three bodies to move): all 28 anchors still resolve, #sharingModel on :9208, #controlled_by_parent on :9209 and :9275. No other anchor resolves only inside those three bodies. Every method-name anchor into the file (#computeControlledByParentFilter at ADR-0055:5, :123 and ADR-0139:246; #assertControlledByParentWrite; #assertMasterRowEditable; #hasPlatformAdminPosture; #collectRLSPolicies; #computeDelegatedReadFilter; #computeRlsFilter; #getReadFilter; the two #SecurityPlugin.… members) resolves on a declaration the class keeps as a method shell under the series' shape, so no move-only cut can break it.
Three MORE anchors of the same class as the two above sit in bodies later cuts move, read now so no later cut discovers them on a built head: ADR-0123:4 #refuseNoActiveOrganization resolves ONLY on the local const refuseNoActiveOrganization = (…) at :8499, inside composeWriteTenantWall (cut 4's write tenant wall); ADR-0055:24 #rlsFilter ONLY on the local const rlsFilter = andComposeLayers(…) at :4359, and ADR-0126:363 #nav_permission_sets ONLY on the literal at :1789, both inside start() (the cut-9+ middleware, over the 3,000-line human-merge line by the seam plan). Four module-level declarations are anchored by symbol and stay where they are under the series' own rule for anchored top-level symbols: #isPrincipalLessContext (:484), #CBP_MAX_CHAIN_DEPTH (:630), #writeCheckPolicies (:1279), #manage_metadata (:233, also :4888).

Ruling 6351993113 on [maintainer] refactor(plugin-auth): split src/auth-manager.ts (10,338 lines, +1,867 in 30 days) along its AuthManager seams, one move-only slice per PR #25224, item 6: 「when a per-file shrink-only ledger names the big file by path and a counted site sits inside a body to be moved, the site is swept in its own PR first, in the ledger's own prescribed direction」; ruling 6348891160 on [maintainer] refactor(service-automation): split src/engine.ts (13,735 lines, +2,199 in 30 days) along its AutomationEngine seams, one move-only slice per PR #25222 (the series' .d.ts bar), unchanged by this ruling.

Ruling: A, as narrowed

Sequencing between two tasks the repo already keeps apart — a move-only cut and a Tier H docs correction — is a named no-escalation class (「技术任务间顺序与依赖」); the anchor reading this ruling adds to the series' proof is 「验证策略」. No floor moves: behaviour is identical (move-only, same suite), the published declarations keep the 6348891160 bar, no gate is loosened (the anchor gate stays green on the real tokens, with no exemption and no planted token), nothing is added. The ADR's words are NOT decided here: the repoint is proposed in its own PR and becomes true only on the maintainer's APPROVED review, which is the Tier H control working as written. The PM answers this fork; it does not go up.

Why not B. AGENTS 14 answers it in as many words: one docs/adr/** path makes the whole 400-line move PR Tier H, and the prescribed cure for a mixed diff is 「split off the governed files」. B would also bury a two-line pointer correction the maintainer must read on its own inside a diff that is, by the card's contract, content-free. And the gate's remedy 「re-anchor it where it lives」, read literally for these two sentences, would point write-path prose at a read module: the sentences name the write half, which does not move in cut 2.

Why not C. The three relation bodies need no anchor edit at all (re-measure above), so holding them behind a Tier H review buys nothing; the series is strictly serial in one thread on one harness-pinned branch, so a cut that waits for the maintainer stalls cuts 3+ with it. 6351993113 ordered a sweep PR first because that sweep was self-landable in the lane; a Tier H docs PR is not, so the order inverts: move what needs no doc edit now, and let the docs PR gate only the bodies that carry the tokens.

Fixed here, so no later cut of this card opens a second decision on the same point:

Cut 2 (narrowed). Moves exactly resolveCbpRelation, reportCbpMasterUnresolved and reportRejectedReferenceAlias into ONE new module beside the file, security-plugin-cbp-relation.ts, with the module-level declarations and imports only those three bodies read; computeControlledByParentFilter, controlledByParentChainRefusal, CBP_LEAF_READ_VERBS, CBP_MAX_CHAIN_DEPTH, CbpRelation and every import they still need stay in security-plugin.ts. The module imports the class type-only (cut 1's shape); ⛔ no new export from security-plugin.ts (the two-way value import of 6352049267 is withdrawn with the narrowing). docs/adr/** untouched. Everything else in 6352049267 stands: shape B hosts, getters for the non-readonly fields, the .d.ts block per 6348891160, skip-changeset, the scripts/adr-anchors/ entry for the new module carrying the ADR-0055 §1 invariant while the security-plugin.ts entry keeps its paragraph (scripts/adr-anchors/ is not a row of the governed register). An amended claim via the relay precedes the PR, carrying Ruling-ref: this comment.
The anchor reading joins the series' report block, every cut from now on (dispatch-gates does not derive it for this change set): node scripts/check-adr-symbol-anchors.mjs at the cut's base AND head, both exit 0 with the printed anchor count; plus the map of every ADR symbol anchor naming the big file, each with the line(s) it resolves on and its class (declaration or literal), classified stays / moves / new module. A cut whose map shows an anchor resolving ONLY inside a body it would move stops BEFORE cutting and takes item 4's route — never a needs_decision after the head is built. The map is measurement with symbol-anchors.mjs's exported functions, ⛔ not a new gate (ask 5).
The body-token anchors go into ONE docs-only card. Cut 2's os-dev-report lists them under out_of_scope_findings, and the services seat files one card under the filing gate (domain:services, S, Tier H, no code), with this reading as its premise: ADR-0055:26 #sharingModel resolves on a local const inside the read derivation and ADR-0055:58 #controlled_by_parent on string literals there, while both sentences describe the by-id write pre-image check; ADR-0123:4 #refuseNoActiveOrganization resolves on a local closure inside composeWriteTenantWall, a body cut 4 moves. The card's PR changes those three anchors and nothing else — ⛔ no prose edit (the gate's header: 「Do not repair prose to clear this gate」), ⛔ no anchor-exempt marker (maintainer-only) — to declaration-class symbols the class keeps as method shells across every cut, so no later move can break them again. Candidate targets, for the PR author to propose and the maintainer to approve or amend: ADR-0055:58 → security-plugin.ts#checkControlledByParentWrite (the §3 gate's entry, :9492); ADR-0055:26 → #checkControlledByParentWrite as well (it is the hook 「to extend with a master-access check」 the sentence names), or a file-level anchor if the author reads the fix(security)[P0]: enforce RLS on by-id writes — close member-edits-others'-records hole (#1985) #1994 pre-image step (inline in start(), step 2.7) as naming no symbol — the gate's remedy for that case; ADR-0123:4 → #composeWriteTenantWall. The PR lands only on an APPROVED review by a GOVERNED_APPROVERS account; the director seat requests it in a Tier H batch; no seat readies, queues or arms it before.
The remainder of cut 2 (computeControlledByParentFilter, controlledByParentChainRefusal, CBP_LEAF_READ_VERBS and the imports only they read) moves in a later cut ONLY after item 3's PR is on main, under the series' usual proof plus item 2's reading, grouped with the write gate or on its own as the thread claims; the same holds for composeWriteTenantWall in cut 4. Until then the bodies stay as they are. ⛔ Never plant a token to keep an anchor green (a const sharingModel, a quoted 'controlled_by_parent'; a comment does not count anyway); ⛔ never move a body an anchor resolves only inside of. If the maintainer declines item 3, those bodies stay in security-plugin.ts for the series' end state and the final report says so; that is not a fork.
Cuts 3 onward are not blocked by items 3 or 4. At 5801a4f2 every other symbol anchor into the file resolves on a method or class declaration the class keeps, on a module-level declaration that stays, or on a token outside the bodies cuts 3–8 move; item 2's reading per cut is what proves it each time. The two start() locals (#rlsFilter ADR-0055:24, #nav_permission_sets ADR-0126:363) are a different case from this ruling's: there the sentence's mechanism itself moves, so the gate's literal remedy 「re-anchor it where it lives」 applies and the cut re-anchors them to the new module in the same PR — a Tier H PR by construction, which that cut already is by the 3,000-line human-merge line; its claim says so up front rather than reporting a fork. A top-level declaration an ADR anchors by symbol (isPrincipalLessContext, CBP_MAX_CHAIN_DEPTH, writeCheckPolicies, the manage_metadata table) stays in security-plugin.ts, by the cut-1 precedent for getObjectSecurityMeta, unless a Tier H repoint lands first.
Premise, falsifiable: at cut 2's base, blanking the three relation bodies leaves every ADR symbol anchor into security-plugin.ts resolving (this thread's reading at 5801a4f2). A later base where that fails — a new anchor into the file, a renamed local — falsifies it: stop and report the fork on this card, ⛔ do not widen the cut, ⛔ do not edit docs/adr/** inside the cut.
A tooling finding, noted not ruled: dispatch-gates --commands derived 62 gates for a change set that moved lines ADR anchors resolve on and did not derive check-adr-symbol-anchors; cut 1 ran it by hand. The card thread lists it in out_of_scope_findings for a domain:cli finding card (「既有门禁…盲区修复」 class); ⛔ no scripts/pm/ edit under this card.

Why A, on the four axes (business standpoint)

① Long-term soundness (weight ≥50%). Two years out, every ADR anchor into this file names a declaration the class keeps — the resolver's own stated preference (「prefers declaration wherever one exists」) — and no split, no renamed local and no reworded message can rot it silently again. A gets there with the ADR corrected once, by the maintainer, on its own three-line diff; B and C reach the same text but hold a content-free move behind a governance review, and B's literal 「re-anchor where it lives」 would point write-path prose at a read module.
② Measured business pull. The maintainer's split order ([Decision] Split the platform's largest, fastest-growing source files (protocol.ts 32,428 lines, +10,002 in 30 days) the way rest-server.ts was split, or leave them #24586 「同意A」), three cards in flight; the controlled-by-parent section is 1,541 lines, 774 from the last 30 days. Zero consumer sees any option: move-only, declarations under the 6348891160 bar.
③ AI-error prevention. Both failure modes stay loud: an anchor whose token moves reds the CI gate (reproduced at 94ef3e320f), and the only quiet cures — an exemption marker, a planted token, a prose edit — are forbidden by name in the gate's header and in items 3 and 4. Item 2 moves the reading BEFORE the cut, so the red is met on the map, not after a built head.
④ Startup no-sprawl. No gate, no script, no changeset, no second module beyond the one the cut needs; one three-line docs PR and two filed findings.

Only-① pick: A. Do ②③④ flip it: no. Effort for the chosen letter: cut 2 re-cut on three bodies (the branch already holds the five-body shape to narrow), one docs card with a three-line PR, one tooling finding.

Execution after the ruling

Thread-read: 6352049267 (the newest comment on this card at this write). The card thread re-cuts cut 2 to the three relation bodies on its branch, posts an amended claim via the relay with Ruling-ref: this comment at line start, and reports with item 2's block; services seat 1 ACCEPTs on it.
The seat files item 3's docs card and item 7's tooling finding from the report; the director seat carries the docs PR to the maintainer in its next Tier H batch.
⛔ Ruling is not dispatching; the thread already holds its slot. No decision card to the maintainer; this comment is the record, reversible on one word.
Cross-lane: none in cut 2. The docs card's PR touches docs/adr/** only (Tier H); the tooling finding is the cli seat's.

It already holds the five-body shape (abdb89ad03, merged with origin/main at 94ef3e320f); the narrowed cut is one more commit on top, and the PR's diff against its merge base 5801a4f2c is the narrowed cut alone.

Why amended: at the five-body head 94ef3e320f, node scripts/check-adr-symbol-anchors.mjs exits 1 (base 5801a4f2c exits 0). ADR-0055:26 security-plugin.ts#sharingModel and ADR-0055:58 security-plugin.ts#controlled_by_parent resolve only on tokens inside computeControlledByParentFilter and controlledByParentChainRefusal. The fork went to review, and ruling 6353073966 chose A.

File surface, cut 2 as ruled (stop on a breach and explain it in the report):

packages/plugins/plugin-security/src/security-plugin.ts: the bodies of resolveCbpRelation, reportCbpMasterUnresolved and reportRejectedReferenceAlias leave for ONE new module beside it, security-plugin-cbp-relation.ts. With them go the one module-level declaration only they read (masterNotWritableRefusal) and the two imports only it reads (controlledByParentMasterRefusal with its comment, and OWD_DELEGATING_ROW_WRITES). Each method stays in the class with its name, signature, docblock and position, and hands its body one host literal of exactly the members that body reads (CbpRelationHost). Methods go as late-bound closures. ql, logger and cbpRelCache go as getters, because none is declared readonly. This is [maintainer] refactor(rest): split packages/rest/src/rest-server.ts (13,701 lines, 70 commits in 30 days) along its register*Endpoints seams, one move-only slice per PR, /meta after #22877 stage 2 #23050's shape B, as cut 1 applied it.
These stay in security-plugin.ts, byte for byte: computeControlledByParentFilter, controlledByParentChainRefusal, CBP_LEAF_READ_VERBS, CBP_MAX_CHAIN_DEPTH, CbpRelation and every import they read (ruling item 1). The module imports the class type-only, and security-plugin.ts gains no export. The two-way value import of 6352049267 is withdrawn.
scripts/adr-anchors/: ONE new entry for the new module, carrying ADR-0055 and the §1 invariant of the existing security-plugin.ts entry. The security-plugin.ts entry stays unchanged.
docs/adr/**: not touched.
Every gate, baseline, docs anchor and test that reads a moved line by path moves in the same PR and stays green. ⛔ No gate is loosened, and none goes silently empty.
.d.ts: ruling 6348891160 item 1, with the same four-hash block, normaliser, raw line count and positive control as cut 1.
No changeset (skip-changeset).
⛔ Not touched: the write gate (checkControlledByParentWrite onward), every other section of the class, any behaviour.

Anchor reading before the cut (ruling item 2): every ADR symbol anchor into security-plugin.ts was mapped with extractAnchors and symbolSegmentResolution from scripts/symbol-anchors.mjs. The map covers 20 distinct symbols and 28 anchors across 10 ADRs. At the narrowed head, each one resolves in security-plugin.ts with the same class it had at the base. #sharingModel stays a declaration and #controlled_by_parent stays a literal, both on the bodies that stay. No anchor resolves only inside the three bodies that move. node scripts/check-adr-symbol-anchors.mjs exits 0 at both base and head, with 2383 anchors, 440 of them declaration-class and 27 literal-class. That holds premise 6 of the ruling.

Since 6352049267, origin/main moved to 09e07c259a. Nothing under packages/plugins/plugin-security/, docs/adr/ or scripts/adr-anchors/ changed, so the reading stands on the PR's base.

Container & model: L series (one cut per PR, strictly serial in this thread), card thread (in-session executor), effort: xhigh (permission boundary). The cut goes back to the services seat 1 for ACCEPT before cut 3 starts.

Claim: card thread · domain:services seat 1 (seat post #6021, project run by the Sales account) · p2 · series card, cut 5 of the security-plugin.ts split: step 3.7's Layer 0 tenant write wall (composeWriteTenantWall) moves out · 2026-10-23T04:02Z
Ruling-ref: 6353073966 (item 4: this body moves once the Tier H docs PR lands; items 2 and 5 for the anchor reading); the series' .d.ts bar stays ruling 6348891160 item 1
Session: session_017BoLT8Gaa8t9a7AWVH8qZa
Account: os-sales (the seat's linked user; the card's assignee)
Branch: claude/project-thread-3fzya4, the harness-pinned branch for this session, restarted from origin/main at 4d7e2b1f38 (cut 4's merge). It names no issue, so this claim is the identity record.
Worktree: objectstack-issue-25223
Domain: domain:services
Seat: domain:services#1 (seat post #6021)

Why now: ruling 6353073966 item 4 held composeWriteTenantWall with the two read bodies until the docs PR for #25314 landed. That PR, #25316, merged as 97967a9a06 (correction 6355907512), and cut 4 moved the two read bodies. On 4d7e2b1f38, ADR-0123:4 anchors security-plugin.ts#composeWriteTenantWall, a method name, which stays as a shell.

File surface, cut 5 (stop on a breach and explain it in the report):

packages/plugins/plugin-security/src/security-plugin.ts: the body of one async method, composeWriteTenantWall (signature :8408 at 4d7e2b1f38), leaves for ONE new module beside it, security-plugin-write-tenant-wall.ts. It is step 3.7's wall, composed once per write: the ADR-0123 D2 scope pre-test, the parts every row is held to (ADR-0095 D1, the delegator's wall under ADR-0090 D10), and the payload and stored-image judgements (group posture: a member whose session has no active organization gets 500 ERR_SYSTEM_WRITE_ORGANIZATION_REQUIRED on a tenant-scoped create, where isolated answers 403 naming the missing organization #24784, a platform operator whose session has no active organization gets 500 ERR_SYSTEM_WRITE_ORGANIZATION_REQUIRED on an insert into a posture-permitting tenant object, under group and isolated alike #24821, group posture: a member's insert whose organization_id names another organization of its membership set is silently stored in the active organization (the engine's read-only strip), where #21666 ruled an explicit value meets the wall and is never rewritten #24822).
- The method stays in the class with its name, signature, docblock and position. It hands its body one host literal of exactly the members that body reads (WriteTenantWallHost): organizationWallRefusal, computeWriteTenantWall and computeWriteTenantCheckFilter as late-bound closures, and tenancyPosture and orgScopingEnabled as getters (the first is not readonly; the second is the class's own getter). This is [maintainer] refactor(rest): split packages/rest/src/rest-server.ts (13,701 lines, 70 commits in 30 days) along its register*Endpoints seams, one move-only slice per PR, /meta after #22877 stage 2 #23050's shape B, as cuts 1 to 4 applied it.
- No module-level declaration moves. WriteTenantWall and WriteWallRefusal keep their one declaration: the method's signature and raiseWriteWallRefusal read them. The module names both through the class's own signature, as cuts 2 to 4 name CbpRelation.
- carriesActiveOrganization stays, because callerHasOrganizationScope reads it too. It gains export, and the module imports it by value, as cut 3's module imports its five values. matchesFilterCondition leaves the @objectstack/formula import of security-plugin.ts, because no code left there reads it.
docs/qa/platform-checklist/areas/access-security.json: two prose citations, items access-security.activation-write-operator-gate and access-security.walled-environment-metadata-operator-only, anchor security-plugin.ts#denyTenantPlacement. That name is a local const inside the moved body, so check-platform-checklist reds ABSENT SYMBOL once the body moves (measured on a trial). Both are re-pointed to the new module in the same PR, the path only. Nothing else in the file changes.
scripts/adr-anchors/: ONE new entry for the new module, carrying ADR-0123 and the ADR-0123 D2 paragraph of the existing security-plugin.ts entry, verbatim. That paragraph is this body's pre-test and its order ahead of the forge guard. The security-plugin.ts entry stays unchanged.
docs/adr/**: not touched.
Every gate, baseline, docs anchor and test that reads a moved line by path moves in the same PR and stays green. ⛔ No gate is loosened, and none goes silently empty.
.d.ts: ruling 6348891160 item 1, with the same four-hash block, normaliser, raw line count and positive control as cuts 1 to 4.
No changeset (skip-changeset).
⛔ Not touched: organizationWallRefusal, computeWriteTenantWall, computeWriteTenantCheckFilter, raiseWriteWallRefusal, writeWallVerdict, the middleware's step 3.7, every other section of the class, and any behaviour.

Anchor and reader reading before the cut (ruling item 2), on 4d7e2b1f38:

Every ADR symbol anchor into security-plugin.ts was mapped with extractAnchors and symbolSegmentResolution from scripts/symbol-anchors.mjs: 27 anchors, 18 symbols, 10 ADRs. With the body blanked, none changes class. ADR-0123:4 #composeWriteTenantWall resolves on the method declaration, which stays.
The same blanking over the non-ADR corpora (spec liveness object.json and permission.json, the platform checklist areas, system-context.mdx, spec conversions/registry.ts) changes exactly the two #denyTenantPlacement citations above, from declaration to unresolved. No other security-plugin.ts# anchor in the repo names a token of the body.
The body holds no isSystem read (one comment names it), so the system-context census has no row to move. It holds no engine write, so the tenant-audit census has no site to move.
No security-plugin.ts:N line citation points into the moved range.
node scripts/check-adr-symbol-anchors.mjs exits 0 at base: 2383 anchors, 440 of them declaration-class and 26 literal-class.

Serial check: of the open PRs, two touch this cut's files, and neither overlaps it.

cloud-connection, plugin-security: a marketplace upgrade that would un-make an access choice is refused until it is confirmed (#24446 U2) #25355 touches security-plugin.ts with one import after :47 and one block at :1720. This cut's hunks are the new import after cut 4's (:145), the @objectstack/formula import (:187), carriesActiveOrganization (:775) and the method body (:8408 onward).
docs(qa): re-author access-security.platform-owner-email-anchor for the Default Organization grant #25323 (draft) touches access-security.json at :2919-:3063. This cut's two lines are :2582 and :3553, and docs(qa): re-author access-security.platform-owner-email-anchor for the Default Organization grant #25323 adds no #denyTenantPlacement citation.

Container & model: L series (one cut per PR, strictly serial in this thread), card thread (in-session executor), effort: xhigh (permission boundary). The cut goes back to the services seat 1 for ACCEPT before cut 6 starts.
Clause-②: no

Ruling item 4 held composeWriteTenantWall with the two read bodies until the Tier H docs PR for #25314 landed; #25316 merged as 97967a9 (correction 6355907512) and cut 4 moved the read bodies, so the hold is over. The body of the one async method composeWriteTenantWall (step 3.7 Layer 0 tenant write wall: the ADR-0123 D2 scope pre-test ordered ahead of the forge guard, the caller and delegator parts, the payload and stored-image judgements of #24784, #24821 and #24822) moved unedited to src/security-plugin-write-tenant-wall.ts. Shape B as in cuts 1 to 4: one host literal typed as the Pick of WriteTenantWallHost over exactly the members the body reads; organizationWallRefusal, computeWriteTenantWall and computeWriteTenantCheckFilter as late-bound closures; tenancyPosture (not readonly) and orgScopingEnabled (the class getter) as getters, so the reads the returned judgements make at call time still read the plugin field then. No module-level declaration moved: WriteTenantWall and WriteWallRefusal stay (the method signature and raiseWriteWallRefusal read them) and the module names both through the class signature; carriesActiveOrganization stays (callerHasOrganizationScope reads it), gains export and is imported by value; matchesFilterCondition leaves the formula import of security-plugin.ts. One reader outside the package moved with the body: two platform-checklist citations in docs/qa/platform-checklist/areas/access-security.json anchored security-plugin.ts#denyTenantPlacement, a local const of the moved body (check-platform-checklist exits 1 ABSENT SYMBOL on a trial without the repoint); both now name the new module, path only. One new scripts/adr-anchors entry (ADR-0123 D2 paragraph verbatim from the security-plugin.ts entry, which is unchanged); docs/adr untouched; no census page touched (no isSystem read, no engine write in the body).

PR #25378	MERGED through the queue (ACCEPT `6358227592`)
`origin/main`	carries `be318db654`

State: the card stays open and dispatched (Part of). security-plugin.ts is now about 9,890 lines, under the 10,000-line line that opened the card. The series continues, because that line decides which files get a card (#24586), not when a card is done, and the card's ask is the seam-by-seam split. The start() middleware has not been cut yet. The card thread claims the next cut, the rest of the tenant write wall, afresh on the merged file. The start() cuts are Tier H and come back to the seat before any PR is opened.

Branch: claude/project-thread-3fzya4, the harness-pinned branch for this session, restarted from origin/main at bdf762c9bd, which carries cut 5's merge be318db654. It names no issue, so this claim is the identity record.
Worktree: objectstack-issue-25223
Domain: domain:services
Seat: domain:services#1 (seat post #6021)

Why now: the landing record 6358687962 hands the card thread the rest of the tenant write wall, claimed afresh on the merged file. The plan in the cut 1 claim 6349703046 groups it with resolveOperationPrincipals, which the wall's write preview calls. No start() code is in this cut.

File surface, cut 6 (stop on a breach and explain it in the report):

packages/plugins/plugin-security/src/security-plugin.ts: the bodies of four async methods leave for two modules beside it. At bdf762c9bd:
- organizationWallRefusal (:8471-:8493), the ADR-0123 D2 scope pre-test that the wall and canWriteObject both ask, and writeWallVerdict (:8580-:8612), the wall's per-row verdict for the write preview (objectql: the validate preview (import dry run) runs no tenant write wall, so after PR #25048 it reports organization_id as dropped for a walled insert that the write stores, and it answers valid for a value the write refuses #25062), join cut 5's body in security-plugin-write-tenant-wall.ts.
- resolveOperationPrincipals (:8953-:9012), the context prologue (ADR-0096 D5, ADR-0090 D10, plugin-security / objectql: an on-behalf-of insert by a crossing platform operator that names no organization may be stamped outside the delegator's organization set (source reading only; measure reach first) #25063), and refuseGuestWithoutOrganization (:9038-:9062), its ADR-0138 D4 guest refusal, go to ONE new module, security-plugin-operation-principals.ts.
- Each method stays in the class with its name, signature, docblock and position. It hands its body one host literal of exactly the members that body reads: methods as late-bound closures, guestOrganizationRefusalWarned (declared readonly) by value, and orgScopingEnabled, tenancyPosture, ql and logger as getters. WriteTenantWallHost gains the members the two new bodies read, and OperationPrincipalsHost is new. This is [maintainer] refactor(rest): split packages/rest/src/rest-server.ts (13,701 lines, 70 commits in 30 days) along its register*Endpoints seams, one move-only slice per PR, /meta after #22877 stage 2 #23050's shape B, as cuts 1 to 5 applied it.
- Three thin adapters stay in the class whole: computeWriteTenantCheckFilter, computeWriteTenantWall and raiseWriteWallRefusal. Each body is shorter than its stub would be.
- Module-level declarations that move: callerHasOrganizationScope and carriesActiveOrganization, which only the moved bodies read, go to the wall module. carriesActiveOrganization loses the export cut 5 gave it, which removes cut 5's import back. The @objectstack/core import of GuestOrganizationUnresolvedError and resolveGuestOrganization, with its comment, goes to the prologue module, because only the guest refusal reads it.
- Module-level declarations that stay and gain export: isPrincipalLessContext (anchored by ADR-0138:152), principalLessDenial (named by that declaration's docblock), isGuestEnvelope (two readers stay) and isTenantWallDenial (named in place by tenant-layer.ts). WriteTenantWall, WriteWallRefusal and WriteWallRowVerdict stay, because the method signatures, raiseWriteWallRefusal and start() read them. The modules name all three through the class's own signatures.
- The postureUsesUnionScope name leaves the @objectstack/spec/security import of security-plugin.ts, because no code left there reads it.
content/docs/permissions/system-context.mdx: row 6c anchors security-plugin.ts#writeWallVerdict, the census site of the body's context.isSystem read. The anchor is re-pointed to the wall module in the same PR, the path only. Nothing else in the file changes.
packages/plugins/plugin-security/src/delegated-organization-membership.test.ts: the plugin-security: delegation probes and diagnostics (canReadObject / canWriteObject / canExport, field mask, explain) answer for an on-behalf-of context the operation prologue now refuses (PR #25101) #25107 enumeration pin lists the files that resolve a delegator. The prologue's one resolution and its one ask move to the new module, so the list gains security-plugin-operation-principals.ts and the test title says three files instead of two. The pin's rule, asks equal resolutions per file, is unchanged.
scripts/adr-anchors/: no change. The wall module's entry (ADR-0123 D2) already describes the pre-test that joins it. No paragraph of the security-plugin.ts entry describes the prologue, so the prologue module gets no entry, as cut 1's module has none.
docs/adr/**: not touched.
Every gate, baseline, docs anchor and test that reads a moved line by path moves in the same PR and stays green. ⛔ No gate is loosened, and none goes silently empty.
.d.ts: ruling 6348891160 item 1, with the same four-hash block, normaliser, raw line count and positive control as cuts 1 to 5. writeWallVerdict is public, so its full signature is in the .d.ts; the stub keeps it.
No changeset (skip-changeset).
⛔ Not touched: composeWriteTenantWall (its moved function stays byte-identical), the three adapters above, canWriteObject, checkControlledByParentWrite, the middleware, every other section of the class, and any behaviour.

Anchor and reader reading before the cut (ruling item 2), on bdf762c9bd:

Every ADR symbol anchor into security-plugin.ts was mapped with extractAnchors and symbolSegmentResolution from scripts/symbol-anchors.mjs: 27 anchors, 18 symbols. With the four bodies blanked, none changes class. ADR-0138:152 #isPrincipalLessContext resolves on the declaration, which stays.
The same blanking over the non-ADR corpora (spec liveness object.json and permission.json, the platform checklist areas, system-context.mdx, spec conversions/registry.ts) changes no anchor's class. Row 6c's #writeWallVerdict still resolves on the method, but the system-context census keys the body's isSystem read by file, so that row moves with the body.
The moved bodies hold no engine write, so the tenant-audit census has no site to move.
No security-plugin.ts:N line citation points into the moved ranges.
node scripts/check-adr-symbol-anchors.mjs exits 0 at base: 2383 anchors, 440 of them declaration-class and 26 literal-class.

Serial check: of the 25 open PRs, none touches security-plugin.ts, the wall module, system-context.mdx, the delegated-organization test or the plugin-security anchor entries.

Container & model: L series (one cut per PR, strictly serial in this thread), card thread (in-session executor), effort: xhigh (permission boundary). The cut goes back to the services seat 1 for ACCEPT before cut 7 starts.

Claim amendment: card thread · domain:services seat 1 (seat post #6021, project run by the Sales account) · cut 6 of the security-plugin.ts split · 2026-10-23T06:40Z
Amends: claim 6358893564
Ruling-ref: 6348891160 (item 1, the series' .d.ts bar); 6353073966 for the anchor reading, unchanged
Session: session_017BoLT8Gaa8t9a7AWVH8qZa
Seat: domain:services#1 (seat post #6021)

One line of the file surface changes, before any push. The claim had principalLessDenial staying in security-plugin.ts and gaining export. It moves to security-plugin-operation-principals.ts instead, beside the one body that throws it (resolveOperationPrincipals), with its docblock, as the base text with export before function.

Why: measured on the first head build. With principalLessDenial exported from security-plugin.ts, its return type makes that file's declarations import errors.ts, and the published dist/index.d.ts then declares PermissionDeniedError and isPermissionDeniedError at the top instead of after the class: a raw diff of 102 lines, one 51-line block moved with its text unchanged. Ruling 6348891160 admits union-order swaps only, and a moved declaration is not one. With the refusal moved, the head .d.ts is byte-identical to base.

One import follows from it: the docblock of isPrincipalLessContext, which stays, names the refusal with a {@link}. security-plugin.ts imports the name type-only from the new module so that link still resolves. A type-only import emits nothing and has no runtime effect, and typecheck and lint pass with it. Every other line of the claim stands: isPrincipalLessContext, isGuestEnvelope and isTenantWallDenial stay and gain export. No other module-level declaration, reader or gate changes.

"summary": "Cut 6 of the security-plugin.ts split; claim 6358893564, amended before the push by 6359105931 (Ruling-ref 6353073966; d.ts bar 6348891160). The bodies of four async methods moved unedited. To src/security-plugin-write-tenant-wall.ts, beside cut 5: organizationWallRefusal (the ADR-0123 D2 scope pre-test the wall and canWriteObject ask) and writeWallVerdict (public; the wall verdict per row for the write preview, #25062). To the new src/security-plugin-operation-principals.ts: resolveOperationPrincipals (the middleware context prologue: ADR-0096 D5 strict mode, ADR-0090 D10 and #25063 delegated organization refusal, the fail-closed set resolution) and refuseGuestWithoutOrganization (ADR-0138 D4). Shape B as in cuts 1 to 5: each method keeps name, signature, docblock and position less async and hands its body one host literal typed as the Pick of WriteTenantWallHost or OperationPrincipalsHost over exactly the members it reads; methods as late-bound closures, guestOrganizationRefusalWarned (readonly) by value, ql, logger, tenancyPosture and orgScopingEnabled as getters. The three thin adapters (computeWriteTenantCheckFilter, computeWriteTenantWall, raiseWriteWallRefusal) stay whole. Module-level: callerHasOrganizationScope and carriesActiveOrganization moved to the wall module (only the moved bodies read them; carriesActiveOrganization loses the export cut 5 gave it, so the wall module no longer imports it back); principalLessDenial (docblock included, plus export) and the @objectstack/core guest import (comment included) moved to the prologue module; isPrincipalLessContext (ADR-0138:152), isGuestEnvelope and isTenantWallDenial stay and gain export; WriteTenantWall, WriteWallRefusal and WriteWallRowVerdict stay and are named through the class signatures; postureUsesUnionScope leaves the spec/security import. The amendment: the claim had principalLessDenial staying exported, but its PermissionDeniedError return type made the published d.ts declare the errors block at the top (102-line raw diff, one 51-line block moved, same text), which the bar does not admit; moved instead, and security-plugin.ts imports the name type-only so the isPrincipalLessContext docblock link still resolves (emits nothing; typecheck and lint pass). Two readers follow the bodies: system-context.mdx row 6c anchor (writeWallVerdict holds the census isSystem read) re-pointed to the wall module, path only; the #25107 per-file enumeration pin in delegated-organization-membership.test.ts lists the new module (1 resolution, 1 ask) and says three files. scripts/adr-anchors and docs/adr untouched.

Base bdf762c: the same counts, VERDICT command-exit 0. The first head commit (before the amendment) gave the same counts. packages/core row-serving-door-exposure.pin.test.ts 3 of 3.

Move proof: each moved body has the same TypeScript AST token sequence as the base body and each of its 117 lines is the base line minus two leading spaces; parameters, return type and async match; two negative controls fail the check (prologue: the delegation branch guard permissionSets.length greater than zero changed to at least zero; wall: the preview first guard isSystem-or-no-user changed to isSystem-and-no-user).

File surface, cut 7 (stop on a breach and explain it in the report):

packages/plugins/plugin-security/src/security-plugin.ts: the bodies of four private async methods go to ONE new module, security-plugin-rls-filter.ts. At 77a77e42f8:
- computeLayeredRlsFilter (:7721-:8133), the ADR-0095 D1 Layer 0 / Layer 1 split before the AND-compose. computeRlsFilter, checkAuthoredRowWrite, explainAccessForCaller, the write wall's adapter computeWriteTenantWall and the middleware in start() call it, and the explain engine reads it through the plugin.
- isVerifiedPlatformOwnerSession (:8178-:8205), the probe the read wall's owner crossing asks (Layer 0: should a verified platform admin cross the org wall by PERMISSION entitlement, not only posturePermitsCrossTenant's three shapes? (cloud#1676 upstream half) #12974).
- computeWriteCheckFilter (:8216-:8305), the ADR-0058 D4 post-image check compile.
- stageRlsMembership (:8343-:8383), the ADR-0105 D11 membership staging both compiles ask.
- Each method stays in the class with its name, signature, docblock and position. It hands its body one host literal of exactly the members that body reads: methods as late-bound closures, the three caches declared readonly (datetimeFieldNamesCache, numberComparandFieldsCache, tenancyDisabledCache) by value, and logger, metadata, permissionEvaluator, ql, rlsCompiler, rlsMembershipResolver and tenancyPosture as getters. RlsFilterHost is new. This is [maintainer] refactor(rest): split packages/rest/src/rest-server.ts (13,701 lines, 70 commits in 30 days) along its register*Endpoints seams, one move-only slice per PR, /meta after #22877 stage 2 #23050's shape B, as cuts 1 to 6 applied it.
- computeLayeredRlsFilter's multi-line return type, the docblocks of its two members included, is repeated on the moved function as the method declares it.
- Three thin members stay in the class whole: computeRlsFilter, hasPlatformAdminPosture and platformFloorYieldsToObjectWriteModel. Each body is shorter than its stub would be.
- Module-level declarations that stay and gain export: writeCheckPolicies (anchored by ADR-0066:112 and the spec liveness ledger) and isCarriedPosture (named in place by the PLATFORM_ADMIN_ONLY_CAPABILITIES docblock). Because of the cut 6 trap (an export whose signature names another file's type moved a declaration in the .d.ts), a local trial build was run before this claim: with both exports in place, the head dist/index.d.ts is byte-identical to base. RlsFilterOptions stays unexported; the module names it through the class's own signature.
- Import names only the moved bodies read leave security-plugin.ts and are imported by the module: computeTenantLayer0Verdict, tenantLayer0FilterOf and TenantLayer0Input (tenant-layer.js), PLATFORM_OWNER_WALL_BYPASS_EVENT (platform-owner-wall-bypass.js), resolvePlatformAdminEmails (@objectstack/core) and RESERVED_RLS_MEMBERSHIP_KEYS (@objectstack/spec/contracts). isConfiguredPlatformAdminEmail and isVerifiedPlatformOwnerRow stay imported there too, because the probe's docblock, which stays, links to both.
scripts/adr-anchors/: no change. No paragraph of the security-plugin.ts entry (ADR-0055, ADR-0106, ADR-0123 D2, ADR-0138 D1) describes the RLS layers, so the new module gets no entry, as cuts 1 and 6's modules have none. check:adr-anchors counts decision letters on the anchored surface only: the moved bodies carry 13 and the new import comment 3, so 2014 drops to 2004. That is disclosed, and no anchor entry is invented for it.
docs/adr/**: not touched.
Every gate, baseline, docs anchor and test that reads a moved line by path moves in the same PR and stays green. ⛔ No gate is loosened, and none goes silently empty. None was found (below), so only the two source files change.
.d.ts: ruling 6348891160 item 1, with the same four-hash block, normaliser, raw line count and positive control as cuts 1 to 6. All four methods are private.
No changeset (skip-changeset).
⛔ Not touched: the three thin members above, getReadFilter, computeDelegatedReadFilter, the tenant write wall's adapters, the middleware, every other section of the class, and any behaviour.

Anchor and reader reading before the cut (ruling item 2), on 77a77e42f8:

Every ADR symbol anchor into security-plugin.ts was mapped with extractAnchors and symbolSegmentResolution from scripts/symbol-anchors.mjs: 27 anchors, 18 symbols. With the four bodies blanked, none changes class. ADR-0055:24 #computeRlsFilter, ADR-0099:317 #hasPlatformAdminPosture, ADR-0105:93 #collectRLSPolicies and ADR-0066:112 #writeCheckPolicies resolve on declarations that stay.
The same blanking over the non-ADR corpora (spec liveness object.json and permission.json, the platform checklist areas, system-context.mdx, spec conversions/registry.ts) changes no anchor's class. The liveness ledger's two #writeCheckPolicies evidence anchors resolve on the declaration, which stays.
isystem-census --json finds no elevation read site in the moved ranges: the probe's isSystem: true is a key of its own system read. tenant-audit-census --json finds no engine write there (the probe's ql calls are reads).
No security-plugin.ts:N line citation points into the moved ranges, and no test or script reads the moved text by path. The plugin-security: delegation probes and diagnostics (canReadObject / canWriteObject / canExport, field mask, explain) answer for an on-behalf-of context the operation prologue now refuses (PR #25101) #25107 enumeration pin counts resolveDelegatorContext(, which the moved bodies do not call.
node scripts/check-adr-symbol-anchors.mjs exits 0 at base: 2384 anchors, 440 of them declaration-class and 26 literal-class.

Serial check: of the 13 open PRs, none touches security-plugin.ts, explain-engine.ts, the rls-* or platform-owner-* sources, the permissions pages or the plugin-security anchor entries.

Container & model: L series (one cut per PR, strictly serial in this thread), card thread (in-session executor), effort: xhigh (permission boundary). The cut goes back to the services seat 1 for ACCEPT before cut 8 starts.

The bodies of four private async methods moved unedited to the new src/security-plugin-rls-filter.ts: computeLayeredRlsFilter (the ADR-0095 D1 Layer 0 / Layer 1 split before the AND-compose, with the platform-admin exemption and the #12974 verified-owner read crossing), isVerifiedPlatformOwnerSession (the fail-closed owner probe, #12974 and #13147), computeWriteCheckFilter (the ADR-0058 D4 post-image check compile) and stageRlsMembership (the ADR-0105 D11 membership staging). Shape B as in cuts 1 to 6: each method keeps name, signature, docblock and position less async and hands its body one host literal typed as the Pick of the new RlsFilterHost over exactly the members it reads; methods as late-bound closures, the three readonly caches (datetimeFieldNamesCache, numberComparandFieldsCache, tenancyDisabledCache) by value, logger, metadata, permissionEvaluator, ql, rlsCompiler, rlsMembershipResolver and tenancyPosture as getters. computeRlsFilter, hasPlatformAdminPosture and platformFloorYieldsToObjectWriteModel stay whole (each body shorter than its stub). computeLayeredRlsFilter's multi-line return type, with the docblocks of its two members, is repeated on the moved function one indentation level in. Module-level: writeCheckPolicies (ADR-0066:112 and two spec liveness evidence anchors) and isCarriedPosture (linked in place by the PLATFORM_ADMIN_ONLY_CAPABILITIES docblock) stay and gain export, imported back by value; RlsFilterOptions stays unexported and the module names it through the class signature; the import names only the moved bodies read leave security-plugin.ts for the module (computeTenantLayer0Verdict, tenantLayer0FilterOf, TenantLayer0Input, PLATFORM_OWNER_WALL_BYPASS_EVENT, resolvePlatformAdminEmails, RESERVED_RLS_MEMBERSHIP_KEYS); isConfiguredPlatformAdminEmail and isVerifiedPlatformOwnerRow stay imported there unchanged because the probe docblock, which stays, links to both. A local trial build checked the cut 6 export trap before the claim. No reader outside the moved code reads the moved lines by path, so only the two source files change. scripts/adr-anchors and docs/adr untouched. Published d.ts byte-identical to base.

Why now: the landing record 6362857718 hands the card thread plan row 6, claimed afresh on the merged file. The plan in the cut 1 claim 6349703046 lists it as permission-set resolution and addressed writes. No start() code is in this cut.

File surface, cut 8 (stop on a breach and explain it in the report). Row 6 has two seams, so the bodies go to TWO new modules in this one PR, as cut 6 split its bodies over two modules.

packages/plugins/plugin-security/src/security-plugin.ts, at 2dfeb1a772:
- To security-plugin-permission-sets.ts (host PermissionSetsHost), the bodies of four private methods:
  - resolvePermissionSetsForContextUnmemoized (:7003-:7085), the resolution itself: positions folded into the request, the human baseline or the agent's restricted ceiling, the post-resolution fallback.
  - dropDeactivatedFoldedSets (:7105-:7122), the activation ledger's say over a folded set.
  - reportNameFoldCollisions (:7279-:7324), the Permission-set resolution binds by POSITION NAME while sys_position_permission_set sits near-empty — confirm name-based resolution is the intended mechanism, not an accident the empty junction hides #13419 / Setup: a position's same-named permission set is in force but invisible — the set's Assigned Users panel is empty and the position reads as granting nothing #24757 name-fold warning.
  - permissionSetMemoKey (:6906-:6915), the memo's key. It reads no member, so its method calls the function directly, as cut 1's extractTargetField does.
- To security-plugin-addressed-writes.ts (host AddressedWritesHost, one member, ql), the bodies of five private methods:
  - addressedByIdWriteId (:7437-:7450) and addressedPredicateWrite (:7486-:7497), the security(data): a by-id write answers 403 for a row the caller cannot read and 404 for an id that does not exist, for principals the write pre-image check does not bind: an existence signal the read door withholds #21771 / security(data): a predicate-scoped update or delete is refused when its predicate matches only rows the caller cannot read, and succeeds with zero rows when it matches nothing: an existence signal the read door withholds #21829 route readers. They read no member.
  - readableRowsScopeForPredicateWrite (:7524-:7556), the security(data): a predicate-scoped update or delete is refused when its predicate matches only rows the caller cannot read, and succeeds with zero rows when it matches nothing: an existence signal the read door withholds #21829 read question.
  - extractSingleId (:7558-:7570). It reads no member. It has no docblock of its own: its docblock is the first of the two above declaresControlledByParent's, and stays there.
  - readRowById (:7613-:7630), the readRowById swallows engine failures into null, so a store outage is indistinguishable from an absent row at every gate that probes with it #7505 by-id read.
- Each method stays in the class with its name, signature, docblock and position, less async, and hands its body one host literal of exactly the members that body reads. Methods go as late-bound closures. The three fields declared readonly (baselinePermissionSets, bootstrapPermissionSets, nameFoldWarned) go by value. logger, metadata, permissionEvaluator and ql go as getters. This is [maintainer] refactor(rest): split packages/rest/src/rest-server.ts (13,701 lines, 70 commits in 30 days) along its register*Endpoints seams, one move-only slice per PR, /meta after #22877 stage 2 #23050's shape B, as cuts 1 to 7 applied it.
- Seven members of the row stay in the class whole:
  - getEffectiveObjectPermissions, resolveFallbackPermissionSets, declaresControlledByParent, callerCannotReadAddressedRow and getCallerPreImage: each body is no longer than its stub would be.
  - resolvePermissionSetsForContext, the memo. Its body calls this.permissionSetMemo.delete(context). The tenant-audit census places that call by the receiver's declared type, a WeakMap the class constructs, and subtracts it. Read through a host, the receiver has no type the census can read. A trial cut measured it: the census exits 1 ([untyped-receiver]) and asks for an UNTYPED_RECEIVERS row, a ledger its own docblock declares shrink-only. So the memo stays.
  - describePositionGrants. Its body calls this.canReadObject(…), and packages/core/src/security/row-serving-door-exposure.pin.test.ts classifies every non-test source file that calls the read admission. Moved, the body would make the new module an unclassified caller, and classifying it is not a move.
- Module-level declarations:
  - Two stay and gain export. readUnlessRefused is shared: absentUnderCallerRead and unreadableUnderCallerRead ask it too. POSITION_NAME_FOLD_EVENT is named in place by the reportNameFoldCollisions docblock, which stays, with a {@link}. Its own docblock says it is deliberately not exported from the package, and that stays true: index.ts exports only SecurityPlugin.
  - The new modules also import, by value, four values that are already exported: isGuestEnvelope (cut 6), and PREDICATE_WRITE_READABLE_ID_CAP, predicateWriteReadableCapError and copyOfCallerPredicate (cut 3, which security-plugin-cbp-write-gate.ts imports from there).
  - The .d.ts was measured before this claim, because of the cut 6 trap (an export whose signature names another file's type moved a declaration in the .d.ts). A local trial build with the whole cut in place produced a head dist/index.d.ts and index.d.mts byte-identical to base: af5dee1b…, the hash cuts 6 and 7 reported.
- Import names only the moved bodies read leave security-plugin.ts, and the modules import them from the same specifiers. They are:
  - MCP_AGENT_PERMISSION_SET_RESTRICTED (@objectstack/spec/ai; that whole import statement goes);
  - readDisabledCatalogNames and withoutOperationPrivateKeys (@objectstack/core);
  - resolveEngineDeleteDispatch and the type EngineDeleteDispatchInput (@objectstack/metadata-core).
    No staying docblock links to any of them.
scripts/adr-anchors/: no change. No paragraph of the security-plugin.ts entry describes these bodies, so neither new module gets an entry, as the earlier modules have none. check:adr-anchors counts decision letters only on the anchored surface. The moved bodies carry 3 (ADR-0138 D3, ADR-0090 D10, ADR-0090 D5), and the new import comments carry none, so the count goes from 2005 at base to 2002 at head. That is disclosed, and no anchor entry is invented for it.
docs/adr/**: not touched.
Every gate, baseline, docs anchor and test that reads a moved line by path moves in the same PR and stays green. ⛔ No gate is loosened, and none goes silently empty. None was found (below), so only the three source files change.
.d.ts: ruling 6348891160 item 1, with the same four-hash block, normaliser, raw line count and positive control as cuts 1 to 7. All nine methods are private.
No changeset (skip-changeset).
⛔ Not touched: the seven staying members above, platformFloorYieldsToObjectWriteModel (row 5, settled in cut 7), every other section of the class, and any behaviour.

Anchor and reader reading before the cut (ruling item 2), on 2dfeb1a772, with the trial cut in place rather than blanked bodies:

ADR anchors: every ADR symbol anchor into security-plugin.ts was mapped with extractAnchors and symbolSegmentResolution from scripts/symbol-anchors.mjs. That is 27 anchors over 18 symbols, and none changes class at the trial head. ADR-0138:427 #SecurityPlugin.resolvePermissionSetsForContextUnmemoized resolves on the method, which stays. Neither new module resolves any of them.
Every security-plugin.ts#… anchor anywhere in the repo (30 symbols, the spec liveness ledger and the platform checklist areas included) resolves with its base class at the trial head: 0 changed.
node scripts/check-adr-symbol-anchors.mjs exits 0 at base and at the trial head, with the same line: 2384 anchors, 440 declaration-class and 26 literal-class.
Censuses, with the two modules tracked (git add -N), compared site by site with the module paths mapped back:
- isystem-census: 148 sites at both ends, 0 differences, none in the modules.
- tenant-audit-census: 238 sites, 0 differences, 174 non-engine subtractions at both ends, exit 0.
Readers by path:
- row-serving-door-exposure.pin.test.ts and operation-private-keys.pin.test.ts (@objectstack/core) pass at the trial head, 8 of 8. The moved bodies call withoutOperationPrivateKeys and declare neither of its symbols.
- The plugin-security: delegation probes and diagnostics (canReadObject / canWriteObject / canExport, field mask, explain) answer for an on-behalf-of context the operation prologue now refuses (PR #25101) #25107 enumeration pin counts resolveDelegatorContext( and delegatedOrganizationRefusal(. The moved bodies call neither.
- No security-plugin.ts:N line citation points into the moved ranges.
Prose that names security-plugin.ts for the position-name fold stays true by method, because SecurityPlugin#resolvePermissionSetsForContextUnmemoized is still there. Those are the lint.yml comment on the Permission-set resolution binds by POSITION NAME while sys_position_permission_set sits near-empty — confirm name-based resolution is the intended mechanism, not an accident the empty junction hides #13419 gate, the message text of check-position-name-fold-loaders.mjs, and the comment in measure-position-name-fold-census.mjs.
- check-position-name-fold-loaders.mjs scans the tree only for references to the HotCRM artifact, which no moved body names. It and its --self-test exit 0 at the trial head.
- measure-position-name-fold-census.mjs scans plugin-security for export const string constants, so it would now see POSITION_NAME_FOLD_EVENT. Run at base and at the trial head, its output is byte-identical: it already refuses on its own failing self-test at base. CI does not run it.

Serial check: of the 13 open PRs, none touches security-plugin.ts, the new module names, explain-engine.ts, delegated-admin-gate.ts, the census scripts, the permissions docs pages, or the plugin-security anchor entry. #25389 edits the scan scope of the two @objectstack/core pins above (an extension-scoped prefilter), not what either pin discriminates on.

Container & model: L series (one cut per PR, strictly serial in this thread), card thread (in-session executor), effort: xhigh (permission boundary). The cut goes back to the services seat 1 for ACCEPT before cut 9 starts.
Clause-②: no

"summary": "Cut 8 of the security-plugin.ts split, row 6 of the cut 1 plan (permission-set resolution and addressed writes); claim 6363282332 (Ruling-ref 6353073966; d.ts bar 6348891160). The row has two seams, so the bodies of nine private methods moved unedited to two new modules in this one PR, as cut 6 did. To src/security-plugin-permission-sets.ts (host PermissionSetsHost): resolvePermissionSetsForContextUnmemoized (positions folded into the request, the human baseline or the agent restricted ceiling, the post-resolution fallback), dropDeactivatedFoldedSets, reportNameFoldCollisions (#13419 / #24757) and permissionSetMemoKey (#10757, called directly). To src/security-plugin-addressed-writes.ts (host AddressedWritesHost, one member, ql): addressedByIdWriteId and addressedPredicateWrite (#21771 / #21829, called directly), readableRowsScopeForPredicateWrite (#21829), extractSingleId (called directly; its docblock stays above declaresControlledByParent with the next one) and readRowById (#7505). Shape B as in cuts 1 to 7: each method keeps name, signature, docblock and position less async and hands its body one host literal typed as the Pick of its host over exactly the members it reads; methods as late-bound closures, the readonly baselinePermissionSets, bootstrapPermissionSets and nameFoldWarned by value, logger, metadata, permissionEvaluator and ql as getters. Seven members of the row stay whole: getEffectiveObjectPermissions, resolveFallbackPermissionSets, declaresControlledByParent, callerCannotReadAddressedRow and getCallerPreImage (each body no longer than its stub); resolvePermissionSetsForContext, the memo, because a trial cut made the tenant-audit census exit 1 on its this.permissionSetMemo.delete() read through a host ([untyped-receiver], asking for a row in the shrink-only UNTYPED_RECEIVERS ledger); and describePositionGrants, because its body calls canReadObject and the core row-serving-door-exposure pin classifies every caller file. Module-level: readUnlessRefused (shared with absentUnderCallerRead and unreadableUnderCallerRead) and POSITION_NAME_FOLD_EVENT (linked in place by the staying reportNameFoldCollisions docblock) stay and gain export, imported back by value; the modules also import isGuestEnvelope, PREDICATE_WRITE_READABLE_ID_CAP, predicateWriteReadableCapError and copyOfCallerPredicate, already exported. Import names only the moved bodies read leave security-plugin.ts for the modules (MCP_AGENT_PERMISSION_SET_RESTRICTED, whose whole spec/ai import goes; readDisabledCatalogNames and withoutOperationPrivateKeys from core; resolveEngineDeleteDispatch and EngineDeleteDispatchInput from metadata-core). A local trial build checked the cut 6 export trap before the claim.

Why now: the landing record 6365547058 hands the card thread plan row 7, claimed afresh on the merged file. The plan in the cut 1 claim 6349703046 lists it as read filters, field readers, object admission (getReadFilter .. canExport). No start() code is in this cut.

File surface, cut 9 (stop on a breach and explain it in the report). Row 7 has three seams, so the bodies go to THREE new modules in this one PR, as cuts 6 and 8 split theirs over two.

packages/plugins/plugin-security/src/security-plugin.ts, at 25f88e899a:
- To security-plugin-read-filter.ts (host ReadFilterHost), the bodies of two methods:
  - getReadFilter (public, :5871-:5954), the row-level scope the service serves to the doors that compile their own statement.
  - computeDelegatedReadFilter (:5993-:6055), the same scope for an on-behalf-of caller, the two legs intersected.
- To security-plugin-field-readers.ts (host FieldReadersHost), the bodies of three private methods:
  - resolveProjectionFieldMask (:6207-:6300), the derivation every field projection shares.
  - computeReadableFields (:6119-:6140), the readable projection both planes answer from.
  - resolveCallerPosture (:6346-:6365), the one posture a caller's gates read.
- To security-plugin-object-admission.ts (host ObjectAdmissionHost), the bodies of four methods:
  - canReadObject (public, :6416-:6457), the object-level read admission.
  - objectReadAdmission (:6493-:6532), its arms over sets already resolved.
  - canWriteObject (public, :6680-:6846), the write admission the preview asks (formula/objectql: relationship traversal in predicates — a validation rule or visibility predicate reads one hop through a lookup (record.crm_account.type); replaces the removed os.lookup declaration (#18318, batch #148) #18682).
  - canExport (public, :6866-:6913), the export axis (用户级 export 权限轴(接入 P1 预留的 userExportAllowed 槽) #3544).
- Each method stays in the class with its name, signature, docblock and position, less async, and hands its body one host literal of exactly the members that body reads. Methods go as late-bound closures. Every field the bodies read is not declared readonly (delegatedAdminGate, logger, metadata, permissionEvaluator, ql, tenancyPosture), so all go as getters. This is [maintainer] refactor(rest): split packages/rest/src/rest-server.ts (13,701 lines, 70 commits in 30 days) along its register*Endpoints seams, one move-only slice per PR, /meta after #22877 stage 2 #23050's shape B, as cuts 1 to 8 applied it.
- Four members of the row stay in the class whole: getReadableFields, getMetadataReadableFields, getWritableFields and getQueryableFields. Each body is no longer than its stub would be.
- Module-level declarations:
  - EMPTY_REQUIRED_PERMISSIONS (:523-:525) is read only by resolveCallerPosture's body, so it moves with it, unedited, as cuts 1 to 4 moved the declarations only their bodies read. Its type, NormalizedRequiredPermissions, stays unexported in security-plugin.ts; the module names it through the class's own signature (the posture's requiredPermissions field), as cut 1's module names ObjectSecurityMeta.
  - The import name intersectFieldMasks (./explain-engine.js) is read only by resolveProjectionFieldMask's body, so it leaves security-plugin.ts's import, and the field readers import it from the same specifier. No staying docblock links to it; canWriteObject's docblock names it in backticks only.
  - isPrincipalLessContext (cut 6) and requiredCapsForOperation are already exported, and the modules import them by value. security-plugin.ts gains no new export, so the cut 6 .d.ts trap does not arise. A local trial build with the whole cut in place produced a head dist/index.d.ts and index.d.mts byte-identical to base (7d67966c…, on 25f88e899a's dependencies).
Two readers outside the moved code read the moved lines by path, and both are re-pointed in this PR, as cut 6 re-pointed the same two:
- content/docs/permissions/system-context.mdx, rows 3, 4, 5, 6 and 6b. check-system-context-census keys each elevation read by file and enclosing symbol, and the five context?.isSystem reads now sit in the new modules. A trial measured it: with the page untouched the census reports 8 problems (3 files without a row, 5 anchors that are no longer read sites). Each anchor's path changes from security-plugin.ts#X to the new module's #X; the symbol, the row text and every other anchor stay. With that, the census exits 0: 148 sites, 140 cited symbols against 140 required, 163 anchors, files 71 to 74.
- packages/plugins/plugin-security/src/delegated-organization-membership.test.ts, the plugin-security: delegation probes and diagnostics (canReadObject / canWriteObject / canExport, field mask, explain) answer for an on-behalf-of context the operation prologue now refuses (PR #25101) #25107 enumeration pin. It lists the files that resolve a delegator, and the five moved bodies that do so (computeDelegatedReadFilter, resolveProjectionFieldMask, canReadObject, canWriteObject, canExport) each ask the organization check beside their resolution. The expected list gains the three modules, and the title says six files instead of three. The rule it pins, asks equal resolutions in every file, is unchanged, and it holds at the trial head: read filter 1 and 1, field readers 1 and 1, object admission 3 and 3, security-plugin.ts 2 and 2.
scripts/adr-anchors/: no change. No paragraph of the security-plugin.ts entry describes these bodies, so no new module gets an entry, as the earlier modules have none. check:adr-anchors counts decision letters only on the anchored surface. The moved bodies carry 27, and the new import comments carry none, so the count goes from 2001 at base to 1974 at head. That is disclosed, and no anchor entry is invented for it:
- getReadFilter 4 (ADR-0056 D2, ADR-0090 D10, ADR-0096 D5, ADR-0139 D5); computeDelegatedReadFilter 4 (ADR-0090 D10 three times, ADR-0123 D2);
- resolveProjectionFieldMask 3 (ADR-0090 D10, ADR-0096 D5, ADR-0106 D7);
- canReadObject 3 and canExport 3 (each ADR-0056 D2, ADR-0090 D10, ADR-0096 D5); objectReadAdmission 2 (ADR-0066 D3, ADR-0090 D10); canWriteObject 8 (ADR-0056 D2, ADR-0066 D3, ADR-0090 D10 twice, ADR-0090 D12, ADR-0096 D5, ADR-0123 D2 twice).
docs/adr/**: not touched.
Every other gate, baseline, docs anchor and test that reads a moved line by path moves in the same PR and stays green. ⛔ No gate is loosened, and none goes silently empty. None other was found (below).
.d.ts: ruling 6348891160 item 1, with the same four-hash block, normaliser, raw line count and positive control as cuts 1 to 8.
No changeset (skip-changeset).
⛔ Not touched: the four staying projections, every other section of the class, the row 8 members (declareEveryone .. checkAuthoredRowWrite), start(), and any behaviour.

Anchor and reader reading before the cut (ruling item 2), on 25f88e899a, with the trial cut in place rather than blanked bodies:

ADR anchors: every ADR symbol anchor into security-plugin.ts was mapped with extractAnchors and symbolSegmentResolution from scripts/symbol-anchors.mjs. That is 27 anchors over 18 symbols, and none changes class at the trial head. The row's three anchored names, #getReadFilter (ADR-0096:181, :182, :183, :199, ADR-0139:222), #computeDelegatedReadFilter (ADR-0139:223) and #SecurityPlugin.getMetadataReadableFields (ADR-0138:153), resolve on the methods, which stay with their docblocks.
node scripts/check-adr-symbol-anchors.mjs exits 0 at base and at the trial head, with the same line: 2384 anchors, 440 declaration-class and 26 literal-class.
The spec liveness ledger's security-plugin.ts#canExport evidence (permission.json, allowExport) resolves on the method, which stays, and allowExport is still named in security-plugin.ts (in canExport's docblock), so its key-mention reading does not change. pnpm --filter @objectstack/spec check:liveness gives byte-identical output at base and at the trial head. The entry's prose, canExport asking checkObjectPermission('export'), stays true by method: the body is one call away. packages/spec/** is not touched.
Censuses, with the three modules tracked (git add -N), compared site by site with the module paths mapped back:
- isystem-census: 148 sites at both ends, 0 differences; the five moved reads sit in the modules.
- tenant-audit-census: 238 sites, 0 differences, 174 non-engine subtractions at both ends; no moved body holds a write verb. check-tenant-audit-census exits 0.
Readers by path:
- row-serving-door-exposure.pin.test.ts and operation-private-keys.pin.test.ts (@objectstack/core) pass at the trial head, 8 of 8. The pin classifies callers of .canReadObject(; no moved body calls it (the canReadObject body is the definition), and security-plugin.ts still calls it, from describePositionGrants and the service binding.
- check-platform-checklist and check-scripts-symbol-anchors give the same output at base and at the trial head.
- No security-plugin.ts:N line citation points into the moved ranges.
- No test replaces or spies on a moved method on the plugin instance.

Serial check: of the 24 open PRs, none touches security-plugin.ts, the new module names, system-context.mdx, delegated-organization-membership.test.ts, the census scripts, the liveness ledger or the plugin-security anchor entry. #25389 and #25410 edit the scan scope of the core read-admission pin (an extension-scoped prefilter), not what it discriminates on.

Container & model: L series (one cut per PR, strictly serial in this thread), card thread (in-session executor), effort: xhigh (permission boundary). The cut goes back to the services seat 1 for ACCEPT before cut 10 starts.
Clause-②: no

Claim amendment: card thread · domain:services seat 1 (seat post #6021, project run by the Sales account) · cut 9 of the security-plugin.ts split · 2026-10-23T13:33Z
Amends: claim 6365993271
Ruling-ref: 6353073966 for the anchor reading, unchanged; 6348891160 (item 1, the series' .d.ts bar)
Session: session_017BoLT8Gaa8t9a7AWVH8qZa
Seat: domain:services#1 (seat post #6021)

One line of the file surface changes, before any push. The claim had scripts/adr-anchors/ unchanged. It gains one entry instead: scripts/adr-anchors/packages__plugins__plugin-security__src__security-plugin-field-readers.ts.json. The entry carries ADR-0106 and the ADR-0106 D7 invariant paragraph of the security-plugin.ts entry, verbatim, as the entries of cuts 2 to 5 carry theirs.

Why: re-read while writing the report. The claim said no paragraph of the security-plugin.ts entry describes the moved bodies, and for one paragraph that is wrong. The ADR-0106 D7 paragraph names getMetadataReadableFields and getReadableFields, which stay. But its metadata-plane half, "the same caller resolves the configured fallback permission set", is the fallbackOnEmptySets branch of resolveProjectionFieldMask, whose body moves to the field-readers module. The body still carries its [ADR-0106 D7] comment there. Cut 4 set the rule for this: its module got an entry because one half of the ADR-0055 §1 paragraph ("reads answer RLS_DENY_FILTER") was the leaf it moved. The security-plugin.ts entry is unchanged, because the two methods, their docblocks and the flag each passes stay in that file.

What this moves, disclosed:

pnpm check:adr-anchors counts 81 anchored files at head instead of 80.
The decision-letter count on the anchored surface goes from 2001 at base to 1977 at head, not 1974. The 3 letters in resolveProjectionFieldMask's body (ADR-0090 D10, ADR-0096 D5, ADR-0106 D7) are on the anchored surface again, in the field-readers module. The 24 in the read-filter and object-admission bodies leave it.
No anchor token is planted, and no docs/adr/** file is touched.

Every other line of the claim stands. No paragraph of the entry describes the read-filter or object-admission bodies:

ADR-0055 §1 is the controlled-by-parent relation, which stays in its cut 2 to 4 modules.
ADR-0123 D2 is the write wall's no-organization refusal, in its cut 5 module. canWriteObject only asks that wall's scope pre-test, as the middleware does.
ADR-0138 D1 is the seed-ownership claim.

So neither of those two modules gets an entry.
